Magna-Power Expands SL Series of Programmable DC Power Supplies to 10kW in 1U with 18 New Models
This article highlights Magna-Power Electronics expansion in SL Series programmable DC power supply product line with the introduction of 18 new models at 10 kW rated output power.
Magna-Power expanded its popular SL Series programmable DC power supply product line with the introduction of 18 new models at 10 kW rated output power, while maintaining the product line’s 1U (1.75” high) rack-mount form factor. The SL Series continues to lead 1U rack-mount programmable DC power supply power density, enabling extremely power dense rack-mount integrations, with continuous full-power operating at ambient operating temperatures from -25°C to 50°C and zero clearance required on top and bottom. The 18 new SL Series models span rated voltages up to 1500 Vdc and rated currents up to 250 Adc, with three-phase AC input options including: 208 Vac, 240 Vac, 380/400 Vac, 415 Vac, 440 Vac, or 480 Vac.
The SL Series was first introduced in 2013 as Magna-Power’s first 1U power supply, at the time offered up to 4 kW—an industry first—building upon over 30 years of innovation in power electronics. Since 2013, the product line was expanded to 6 kW in 2015, 8 kW in 2018, and now 10 kW, through its innovative power electronics layout and continued internal innovations in heat transfer, new magnetic designs, and integration of the latest generation of silicon carbide semiconductors. The SL Series, now achieving up to 95% efficiency, has grown into Magna-Power’s most popular product line, satisfying the application demands for: automated test equipment (ATE) system integration, semiconductor and laser diode burn-in, electric vehicle and aerospace testing, and general research and development.

All SL Series models come standard with monitoring and control from a variety of sources, including: front panel, computer interface and an isolated analog-digital I/O connector for PLC integration. A Standard Commands for Programmable Instrumentation (SCPI) command set is supported for control from virtually any programming language, including Python. In addition, an IVI driver is included for the Visual Studio programming environment along with a dedicated National Instruments LabVIEW™ and LabWindows™ driver. Additional computer interface options include LXI TCP/IP Ethernet (+LXI), IEEE-488 GPIB (+GPIB), USB and RS-485. With the Ruggedized (+RUG) option, the SL Series meets MIL-STD-810G shock and vibration standards. Ultra-high stability and precision applications, such as for magnet steering, can be met by combining the SL Series with the DBx Module. Similarly, high-power battery charging or back-emf protection can be achieved in combination with the BDx Module.
Standard protection features on the SL Series DC power supplies include a dedicated interlock input, programmable over voltage trip and over current trip settings, thermal protection, fuse fault, and analog input programming line fault. In addition, when in standby or fault condition, a 3-phase contactor provides a mechanical break between the power supply’s power processing circuit and the AC mains, providing the user confidence of safe operating conditions.
The new 10 kW SL Series models are available immediately. All Magna-Power products are designed and manufactured at the company’s vertically integrated headquarters in Flemington, New Jersey USA. The company’s products are available directly from Magna-Power in the USA, through Magna-Power sales offices in the United Kingdom and China, or from a network of distributors in over 40 countries worldwide.
Magna-Power designs and manufactures robust programmable power products in the USA that set industry standards for quality, size, and control. The company’s experience in power electronics is reflected in its 1.25 kW to 2000 kW+ product line, quality service, and reputation for excellence. Today, you will find Magna-Power’s standard products at its thousands of customers worldwide, aiding in the manufacture of electric vehicles, simulating solar arrays for development of inverters, steering magnets for particle accelerators, powering radar systems, driving traction controllers for locomotive development, or at a wide range of Universities for cutting-edge energy research. Founded in 1981 originally with the intent of being a power electronics, lighting, and magnetics research and development company, Magna-Power pivoted several times before becoming the high-power product design and manufacturer that it is today. Learn more about the company's story and the path that eventually led it to the vertically integrated volume manufacturer that it is today. Magna-Power Electronics products are proudly made in the USA at the company's vertically integrated, company designed and owned 73,500 ft2 headquarters in Flemington, New Jersey. All engineering, manufacturing and North America product servicing is performed at the company's headquarters. Magna-Power Electronics utilizes vertical integration in its manufacturing process for complete control over quality, cost, and lead-time of its made-to-order products. As the company has grown, more operations have been internalized. Vertical integration enables Magna-Power to manufacture a very broad line of sophisticated electronic products, while still maintaining industry leading lead-times. Housing engineering and manufacturing teams in the same facility forces strong collaboration between the two teams for continual process and product improvements.
